	AstronomicalUnit = fun(LightYears);
	cout << LightYears << " light years = " << AstronomicalUnit << " astronomical units." << endl;
	cin.get();
	cin.get();
	return 0;
}

7：

//practice 7
#include<iostream>
using namespace std;

void ShowTime(int hour, int minute)
{
	cout << "Time:" << hour << ":" << minute << endl;
}

int main()
{
	int hour = 0;
	int minute = 0;
	cout << "Enter the number of hours:";
	cin >> hour;
	cout << "Enter the number of minutes:";
	cin >> minute;
	ShowTime(hour, minute);
	//cin.get();
	//cin.get();
	return 0;
}
